Question

For two molecules to react, they must collide at just the right angle and with enough energy to break the original bonds and form new ones. Based on these facts, why does the reaction tend to go more quickly at higher temperatures?

Answer 1

At higher temperatures, molecules move faster and have higher kinetic energy. As a result, they collide more frequently and with greater force. The increased frequency of collisions increases the chances of molecules colliding at the right angle and with sufficient energy to break the original bonds and form new ones. Consequently, higher temperatures generally lead to more successful collisions, accelerating the reaction rate.
